Examining the Feasibility of Using Pressure Gradient Regulated Automated Cerebral Spinal Fluid Drainage During External Lumbar Drain Trials

Participants will undergo lumbar drainage using the Intellidrop automated cerebrospinal fluid drainage system that monitors intracranial or spinal pressure and manages external drainage of cerebrospinal fluid and other body fluids to a user selected pressure target or volume target. Its closed loop, gravity-based drainage ensures natural flow, while offering position-agnostic precision control to achieve an hourly target volume. It connects to the distal end of the lumbar catheter outside the body and replaces the drainage collection device and manual nursing effort.

Participants will undergo lumbar drainage using the Intellidrop automated cerebrospinal fluid drainage system that provides continuous intracranial pressure monitoring and automated control of CSF removal. It is programmed to withdraw small frequent volumes of CSF within predefined safety limits reducing the need for manual stopcock adjustments and minimizing human error. It is designed to improve workflow efficiency, enhance patient mobility, and evaluate the device;s feasibility, performance and safety during the lumbar drain.
